Quote from SAFIN:
Look at GET (Global Electronic Trading) IM using them for futures and cash equities. 19 markets with many contracts.
Take a look at www.getfinancial.com.au/ Fees from USD 6.00 to 0.30 depending on monthly activity.
If you are looking for high frequency trading you should PM me as my friend is a broker there and can negotiate discounted rates.
Doesn't look comparable to IB. No API. Very restricted order types. Horrible commish on low volume futures. Crappy web site.
